Effect of Particle Size of BNT Filler on Dielectric and Mechanical Properties of LCP Based Composite

Abstract:

The effect of particle size of BNT filler on the microstructure, dielectric and mechanical properties of the x BNT - (1-x) LCP composites (x = 40 Vol.%) was investigated with SEM, Impedance analyzer and Universal Test Machine, where BaNd₂Ti₄O₁₂ (hereinafter referred to as BNT) and Liquid Crystal Polymer (hereinafter referred to as LCP). BNT fillers of median particle size of 2.45, 1.39 and 0.69 um were obtained by ball milling for 24, 48 and 72 hours, respectively. BNT and LCP powder were mixed uniformly with twin screw type extruder. Disk samples of 20 mm in diameter and 1 mm in thickness were fabricated with hot press using mixture. As the particle size of BNT filler decreases from 2.45 to 0.69 um, the dielectric constant of composite measured at 10 kHz increases monotonically from 4.8 to 7.2 and its tan δ increases linearly from 0.0052 to 0.0068. Its flexural strength also enhanced with increasing the particle size of BNT filler. It was observed that the smaller particle size of BNT filler is more effective for increasing both dielectric constant and mechanical strength of BNT - LCP composite.
